Perhaps a little housekeeping can get this back on track. Back in the BBS days I wrote volumes on the Wittenberg Door (note the CORRECT spelling) BBS. I was the owner of the site. All sorts of ideas were discussed, but most were on faith/atheism/philosophy/apologetics, etc. Of course in those pre-internet days, only one person could be logged on at a time, and we needed a dedicated phone line. There were probably more than 20 active BBSs in Hamilton at that time, and we had a lot of activity.
This seems to be as close to the old BBS as it gets.
My 2 cents regarding the so-called holy grail: After the “last supper,” someone did the dishes. End of story.
